iStore 180L hot water

Offering premium efficiency and performance, the iStore 180 L - Air to Energy is the perfect choice for smaller homes that want the best in hot water all year round, powered by the sun's rays.

  • iStores premium Australian engineering captures energy in the air to generate environmentally friendly hot water to multiple taps in your home - 24x7 x 365    
  • The iStore uses advanced technology to store 4 kW of heat energy for every 1 kW of power consumed.
  • The iStore consumes 75% - 85% less energy than conventional hot water systems.
  • External wrap around heating coil provides maximum thermal energy transfer.
  • The iStore offsets 2.9 tonnes of CO2 per-annum on an Australian average home.
  • All-in-one integral unit, the iStore is easy and quick to install.
  • Save thousands with federal and state Government incentives.


Heating hot water for your home accounts for up to a quarter of your electricity costs for the average Australian household.
The iStore  reduces hot water heating consumption by two thirds from conventional electric or gas storage systems, while reducing CO2 emmissions by 4 tonnes. Installing an iStore could save you up to $1,000* per year on your energy bills.

A significant reduction in running costs while providing a sustainable source of hot water

The iStore reduces energy consumption by two thirds when compared to conventional electric or gas storage systems, all while reducing the Co2 emissions of your home by as much as 4 tonnes annually.

The 180L iStore uses exclusive technology to provide 400% efficiency

Here's how it works

  1. A fan draws in air, containing heat energy, across the evaporator
  2. The evaporator turns the liquid refrigerant into a gas
  3. The compressor pressurises the refrigerant into a hot gas
  4. The hot gas inside the condenser coil heats the water inside the coil-wrapped tank
  5. The refrigerant reverts back to a liquid after heating the water and continues to the evaporator for the process to start again


The iStore boasts 4 intelligent operating modes adapting to all situations, including a hybrid mode for when additional guests are staying in your home.

Optimal design

External wrap around ALL COPPER heating coil and dual anodes for superior system longevity.

Easy to install

The iStore is easy and quick to install.

Energy Efficient

The iStore consumes approximately 500 W of energy per hour during the air-to-energy heating process

Money & Energy savings

Heating water for the home accounts for up to 30 % of the total energy usage for the average Australian household. iStore can reduce CO2emissions by up to 4 tonnes.

Market Leader

COP - The coefficient of performance is a ratio used to measure the efficiency of electricity consumption vs heating output. The iStore 180L has a PEAK COP of 6.85 which equates to 6.85 kW of heating output for every kW of energy consumed

Energy Efficiency:

    • Hot water heat pumps are highly energy efficient, using renewable energy sources like ambient air or ground heat to heat water.
    • They can achieve a high coefficient of performance (COP), meaning they produce more energy output (heat) compared to the energy input (electricity).

Cost Savings:

    • By utilizing ambient heat sources, hot water heat pumps can significantly reduce energy consumption and lower utility bills compared to traditional heating methods.
    • They provide long-term cost savings due to their energy efficiency and potential eligibility for government incentives or rebates.

Environmental Friendliness:

    • Hot water heat pumps produce fewer greenhouse gas emissions compared to conventional heating systems that rely on fossil fuels.
    • By utilizing renewable energy sources, they contribute to reducing carbon footprints and promoting a more sustainable approach to heating water.

Versatility and Adaptability:

    • Hot water heat pumps can be installed in various settings, including residential homes, commercial buildings, and industrial applications.
    • They can be integrated with existing heating systems or used as standalone units, providing flexibility and adaptability to different heating requirements.

Heat Recovery:

    • Some hot water heat pumps have the ability to recover waste heat from sources like air conditioning or refrigeration systems, further enhancing their energy efficiency.
    • This heat recovery feature allows for simultaneous cooling and water heating, maximizing energy utilization and reducing overall energy waste.
